Further, in a positionabove the substrate delivering/receiving section 8 is disposed a heater51 that performs heat treatment on the semiconductor wafer W with afirst predetermined temperature. Between the heater 51 and substratedelivering/receiving section 8 is disposed a heater 52 that performsheat treatment on the semiconductor wafer W with a second predeterminedtemperature lower than the first temperature. In a position under thesubstrate delivering/receiving section 8 is disposed a plurality oftemperature adjustment mechanisms 53 to adjust (cool) the temperature ofthe semiconductor wafer W treated in the heaters 51 and 52 to apredetermined temperature, for example, the temperature substantiallythe same as the ambient temperature inside the process unit section PU,for example, the temperature of substantially 23° C.

In addition, the substrate carrying mechanism TR1 carries thesemiconductor wafer W to/from the temperature adjustment mechanisms 53and heaters 51 and 52, while the substrate carrying in/out mechanism 2is configured not to be able to access the mechanisms 53 and heaters 51and 52. Further, openings 54 on the process unit section PU side of thesubstrate delivering/receiving section 8, temperature adjustmentmechanisms 53 and heaters 51 and 52 are configured to be openable andclosable by an opening/closing mechanism not shown, for example, ashutter. A filter section not shown is provided above each of thesubstrate carrying in/out mechanism section U2 of the cassette unitsection CU, process unit section PU and interface unit section IFU, andconfigured to supply the temperature/humidity air with the temperatureand humidity of respective set values to each of the units. Thetemperature/humidity air is configured to be set at a predeterminedamount by each exhaust setting mechanism to be recovered from an exhausthole provided under each unit, and it is thus configured that adown-flow of the temperature/humidity air is formed inside each unit.

Further, the pressure of each of the substrate carrying in/out mechanismsection U2 of the cassette unit section CU, process unit section PU andinterface unit section IFU is set by the exhaust setting mechanismthereof so that the pressure of the process unit section PU is set to behigher than both the pressure of the substrate carrying in/out mechanismsection U2 of the cassette unit section CU, and the pressure of theinterface unit section IFU, and that the pressure inside the exposureapparatus 3 is set to be higher than the pressure of the interface unitsection IFU. It is thus configured to prevent unnecessary mist fromentering the process unit section PU or exposure apparatus 3 to be afactor having an adverse effect on the processing of the semiconductorwafer W. Further, as compared with the level of oxygen and/or acid gas(NOX, SOX, H₂S, CO₂ and the like), base gas (ammonia, amine and thelike), and/or moisture contained in the atmosphere of the cassette unitsection CU, the level contained in the atmosphere of the process unitsection PU and/or interface unit section IFU is substantially set to belower than the level of the section CU. This is because of improving theyield of the processing of the semiconductor wafer by reducing effectsof the gases particularly in the processing prior or subsequent toexposure.

As shown in FIG. 7, the substrate carrying in/out mechanism 6 in theinterface unit section IFU is configured to be self-propelled movable inthe X direction (X axis), and provided with an arm 55 configured to bemovable in the vertical direction (Z axis), extendable direction (Yaxis) and rotation direction (θ axis). Further, a wall 56 is providedbetween the interface unit section IFU and process unit section PU,configured to interrupt the atmosphere between the space inside theinterface unit section IFU and the space inside the process unit sectionPU, and provided with an opening 57 of the substratedelivering/receiving section 9. The opening 57 is configured to beopenable and closable by an opening/closing mechanism not shown, forexample, a shutter.

A height position h6 of the opening 57 is set at a position lower than aheight position h7 of an opening 58 of a heating processing chamber FH.Further, the opening 57 is disposed in a position higher than a heightposition of the arm 55 when the arm 55 of the substrate carrying in/outmechanism 6 travels in the X direction (the longitudinal direction ofthe interface unit section IFU). The relationship of the height positionis that the height position h6 of the opening 57> height position of thearm 55 of the substrate carrying in/out mechanism 6 when the arm 55travels in the X direction> height position h7 of the opening 58 of theheating processing chamber FH. It is thus configured to prevent the heatfrom the heating processing chamber FH and/or mist from the heatingprocessing chamber FH and/or substrate carrying in/out mechanism 2 andlike from entering the process unit section PU side. In addition, theheight position h6 of the opening 57 is set to be substantially the sameas the height position h5 of the opening 47, and thus configured toimprove the efficiency of carrying by the substrate carrying mechanism10. In addition, under and above the substrate delivering/receivingsection 9 are disposed the heaters or temperature adjustment apparatusesconfigured to be stacked in the same way as in the substratedelivering/receiving section 8.

As shown in FIG. 8, the heating processing chamber FH is provided with arectangular temperature adjustment mechanism 60 that adjusts (cools) thetemperature of the semiconductor wafer W to a predetermined temperature,for example, the ambient temperature inside the interface unit sectionIFU, for example, to substantially 23° C., and a heating mechanism 61that performs post exposure baking (PEB) on the semiconductor wafer Wsubjected to the exposure processing in the exposure apparatus 3 at apredetermined temperature. The temperature adjustment mechanism 60 isconfigured to be movable in the X direction (X axis), and moving up/downmechanisms 62 are provided under the temperature adjustment mechanism 60in the home position of the mechanism 60 and in a position lower thanthe heating mechanism 61 to be configured to be able to deliver andreceive the semiconductor wafer W to/from the temperature adjustmentmechanism 60 and heating mechanism 61, respectively. Each of the movingup/down mechanisms 62 has a plurality of support mechanisms, forexample, support pins 64 on a base 63, and is configured to be able tosupport the semiconductor wafer W from the backside in point contact bythe support pins 64.

The temperature adjustment mechanism 60 is further provided with notches65 not in contact with the support pins 64 of the moving up/downmechanism 62 on the heating mechanism 61 side, and configured to travelto a position above the heating mechanism 61 to be able to deliver andreceive the semiconductor wafer W using the support pins 64 of themoving up/down mechanism 62 on the heating mechanism 61 side. Inaddition, the opening 58 is provided in the X direction (thelongitudinal direction of the heating processing chamber FH), and isconfigured to be openable and closable by an opening/closing mechanismnot shown, for example, a shutter. The moving up/down mechanism 62 onthe temperature adjustment mechanism 60 side is configured to be able todeliver and receive the semiconductor wafer W to/from the arm 55 of thesubstrate carrying in/out mechanism 6, as well as delivering andreceiving the wafer W to/from the temperature adjustment mechanism 60.

As shown in FIG. 9, each of the heaters HP1 to HP4 and the like of theheater HP blocks HPB1 to HPB4 has substantially the same configurationas that of the heating processing chamber FH, and is provided with arectangular temperature adjustment mechanism 70 that adjusts (cools) thetemperature of the semiconductor wafer W to a predetermined temperature,for example, the ambient temperature inside the process unit section PU,for example, to substantially 23° C., and a heating mechanism 71 thatheats and treats the semiconductor wafer W at a predeterminedtemperature. The temperature adjustment mechanism 70 is configured to bemovable in the Y direction, and moving up/down mechanisms not shown areprovided under the temperature adjustment mechanism 70 in the homeposition of the mechanism 70 and in a position lower than the heatingmechanism 71 and configured to be able to deliver and receive thesemiconductor wafer W to/from the temperature adjustment mechanism 70and heating mechanism 71, respectively. Each of the moving up/downmechanisms has a plurality of support mechanisms, for example, supportpins and is configured to be able to support the semiconductor wafer Wfrom the backside in point contact by the support pins.

The temperature adjustment mechanism 70 is further provided with notches72 not in contact with the support pins of the moving up/down mechanismon the heating mechanism 71 side, and configured to travel to a positionabove the heating mechanism 71 to be able to deliver and receive thesemiconductor wafer W using the support pins of the moving up/downmechanism on the heating mechanism 71 side. In addition, the opening 16of each of the heaters HP1 to HP4 is provided in the Y direction (thelongitudinal direction of the heating processing chamber FH), and isconfigured to be openable and closable by an opening/closing mechanismnot shown, for example, a shutter. The moving up/down mechanism on thetemperature adjustment mechanism 70 side is configured to be able todeliver and receive the semiconductor wafer W to/from the arm 11 of thesubstrate carrying mechanism 10, as well as delivering and receiving thewafer W to/from the temperature adjustment mechanism 70.

Further, as shown in FIG. 10, each temperature adjustment mechanism 70is provided with a flowing path 78 to flow a cooling medium, forexample, cooling water to set the temperature adjustment mechanism 70 ata predetermined temperature, for example, substantially 23° C. Theflowing path 78 is configured to supply the cooling water from a coolingmedium supply mechanism 81 via a pipe 82. For example, it is configuredthat the cooing water supplied to the temperature adjustment mechanism70 of the heater HP4 from the cooling medium supply mechanism 81 as thecooling liquid supply mechanism is supplied to the flowing path 78 ofthe temperature adjustment mechanism 70 of a subsequent-stage heater,for example, heater HP3 by a connection pipe 79 via the flowing path 78,the cooing water supplied to the temperature adjustment mechanism 70 ofthe heater HP3 is supplied to the flowing path 78 of the temperatureadjustment mechanism 70 of a subsequent-stage heater, for example,heater HP2 by the connection pipe 79 via the flowing path 78, and thatthe cooing water supplied to the temperature adjustment mechanism 70 ofthe heater HP2 is supplied to the flowing path 78 of the temperatureadjustment mechanism 70 of a subsequent-stage heater, for example,heater HP1 by the connection pipe 79 via the flowing path 78.

Further, the cooling water from the flowing path 78 of the temperatureadjustment mechanism 70 of the heater HP1 is returned to a coolingmedium recovery mechanism 82 via a pipe 80 that collects the coolingmedium. In addition, it is configured in this embodiment that thecooling water flows from the heater HP4 side to the heater HP1 side, butthe flow of the cooling water can be set as appropriate. Further, asshown in FIG. 11, it is configured that the cooling medium supplymechanism 81 and cooling medium recovery mechanism 82 are managed on abasis of a horizontal block of the heaters, and that cooling water ports90 (for the heater block HPB1) and 91 (for the heater block HPB2) ineach of which the cooling medium supply mechanism 81 and cooling mediumrecovery mechanism 82 are arranged are disposed for heaters HPB1 toHPB4. In addition, not shown in FIG. 11, the cooling water port for theheater block HPB3 is “92” as shown in FIG. 12, and the cooling waterport for the heater block HPB4 is “93” as shown in FIG. 12.

As shown in FIGS. 12 and 13, the cooling water ports 90 to 93 aredisposed in predetermined positions of the process unit section PU. Thecooling water ports 90 to 93 are configured to be connected to a utilityapparatus disposed outside the apparatus, for example, a cooling mediumutility apparatus 100 via respective pipes 101 corresponding to thecooling water ports 90 to 93. The cooling medium utility apparatus 100is provided with ports 90 a to 93 a corresponding to the cooling waterports 90 to 93. Further, the cooling medium utility apparatus 100 isprovided with a water introduction port 106 that takes in the water forcooling water from the outside of the cooling medium utility device 100,and with a water discharge port 107 that discharges the cooing waterused in the substrate processing apparatus 1 from the ports 90 a to 93a.

Further, the cooling medium utility apparatus 100 is provided with atleast one temperature adjustment mechanism, for example, temperatureadjustment mechanisms 102 and 103 to set the water as a cooling mediumintroduced from the water introducing port 106 at a predeterminedtemperature used in the substrate processing apparatus, for example, atsubstantially 23° C., by instructions from a control mechanism 105. Thecooling water set for the predetermined temperature by the temperatureadjustment mechanisms 102 and 103 is configured to enable switching toselect between switching mechanisms, for example, a switching mechanismSW1 route and switching mechanism SW2 route each comprised of a valveand the like, by instructions from the control mechanism 105, and to besent from the temperature adjustment mechanism 102 or 103 collectivelyto the substrate processing apparatus 1 from respective OUT sides viathe ports 90 a to 93 a. In addition, in this embodiment, a plurality oftemperature adjustment mechanisms, i.e. two temperature adjustmentmechanisms, 102 and 103, are provided, but naturally, one temperatureadjustment mechanism may support the apparatus.

Described next is another embodiment of the cooling medium supplymechanism 81 and cooling medium recovery mechanism 82 describedpreviously. As shown in FIG. 14, the cooling water supplied from thecooling medium supply mechanism 81 is configured to be once branched toa plurality of flows by a branch mechanism 99, and supplied to thetemperature adjustment mechanism of each heater of the horizontal blockof the heaters. Further, the cooling water recovered from thetemperature adjustment mechanism of each heater is configured to becollectively recovered to the cooling medium recovery mechanism 82.Thus, the cooling water is supplied independently via each supply lineto the temperature adjustment mechanism of each heater, and it is thuspossible to provide the apparatus with a higher level of safety.

Described next is the switching between the switching mechanisms SW1 andSW2. It is assumed that the cooling water is first sent from the OUTside of each of the ports 90 a to 93 a to the substrate processingapparatus 1 via the switching mechanism SW1 route. The cooling waterflows for each horizontal block of heaters, i.e. flows into the heatersHPB1 to HPB4, and recovered to the IN side of each of the ports 90 a to93 a for each horizontal block. The IN side of each of the ports 90 a to93 a of the recovered cooling water is provided with a temperaturedetecting mechanism that detects the temperature of the recoveredcooling water for each of the ports 90 a to 93 a. The information of thetemperature detecting mechanisms is managed by the control mechanism105, and it is configured that when at least one of respectivetemperature detecting mechanisms of the IN sides of the ports 90 a to 93a detects a value outside set range values, the control mechanism 105switches from the switching mechanism SW1 route to the switchingmechanism SW2 route, while transmitting a first abnormal signal to acontrol mechanism of the substrate processing side to report theinformation. Thus, the cooling water is managed for each horizontalblock of the heaters.

In addition, the temperature adjustments mechanisms may not beparticularly provided on the OUT sides of the ports 90 a to 93 a of thecooling water. This is because the temperature of the sent cooling wateris managed by the temperature adjustments mechanisms 102 and 103.Further, when the detecting mechanism detects a value outside the setrange values also after switching to the switching mechanism SW2 route,the recovery line falling outside the set range temperature values amongthe IN sides of the ports 90 a to 93 a is configured to transmit asecond abnormal signal to the control mechanism of the substrateprocessing apparatus 1 side to report the information. The temperatureof the temperature adjustment mechanism 70 of each heater HP isconfigured to be detected by a temperature detecting mechanism, but itis not clear on whether the cooling medium utility apparatus 100 has theproblem or the temperature adjustment mechanism 70 of each heater HP hasthe problem. Therefore, the control mechanism of the substrateprocessing apparatus 1 side is configured to judge the abnormalcondition based on the information of the temperature detectingmechanism of the temperature adjustment mechanism 70 of each heater HPand the above-mentioned first and/or second abnormal signal to be ableto identify a location of the problem. It is thus configured to greatlyimprove the safety of the apparatus itself by management of thehorizontal block and the dedicated temperature detecting mechanism ofthe temperature adjustment mechanism 70 of each heater.

Further, for utility, for example, supply of a gas with adjustedpredetermined temperature and humidity to each of liquid processingapparatuses of each of horizontal blocks HBB, COTB, DEVB1 and DEVB2, asshown in FIG. 15, it is configured that a utility apparatus disposedoutside the substrate processing apparatus 1, for example, a gas utilityapparatus 120 that supplies the gas with adjusted predeterminedtemperature and humidity sends the gas to ports WPFP1 to WPFP4 providedin predetermined positions of the substrate processing apparatus 1independently through a number of lines corresponding to the numberhorizontal blocks HBB, COTB, DEVB1 and DEVB2, in this case, through fourlines via ports W1 to W4 of the gas utility apparatus 120. Further, bygas branch mechanisms WPF1 to WPF4, the gas sent to the ports WPFP1 toWPFP4 is configured to be supplied to each liquid processing apparatusof each liquid processing apparatus horizontal block via an independentpipe 110, respectively.

Furthermore, as shown in FIG. 16, in the gas utility apparatus 120, theports W1 to W4 are provided in an upper position of the apparatus 120.The reason of such installation is that the footprint of the apparatuscan be decreased. Further, the gas utility apparatus 120 is configuredto take a gas prior to adjustments of the temperature and humidityinside the apparatus from outside the apparatus through a gasintroducing portion 122 via a filter 121. The gas taken in through thegas introducing portion 122 is taken in a cooling portion 123 as thefirst space portion, and it is configured that cooling plates 126 eachin a predetermined shape, for example, in the shape of a rectangle,provided in a cooling medium flowing pipe 125, are cooled by a coolingmedium flowing through the cooling medium flowing pipe 125 of a cooingmedium supply mechanism 124 and that the introduced gas can be cooled.Further, in a position above the cooling plates 126 is provided anintroducing portion 128 as a path (flowing portion) to introduce the gascooled by the cooling plates 126 to a second space portion 127.

In addition, for the relationship between the introducing portion 128and cooing plates 126, as shown in FIG. 17, it is configured that theintroducing portion 128 is disposed in part of the region of the coolingplates 126, for example, in the region of one end, and that the heightof the cooling plates 126 b disposed in positions under the introducingportion 128 extends to a position higher than the height of coolingplates 126 a in positions except the positions immediately under theintroducing portion 128. This is because of the effects of cooling thegas in the entire region of the cooling portion 123, and sending thecooled gas to be sent to the introducing portion 128 to the vicinity ofthe introducing portion 128 without changing the temperature of thecooled gas. Further, for connection between a plurality of coolingplates 126 and cooling medium flowing pipe 125, it is preferable thatthe plurality of cooling plates 126 is inserted in the cooling mediumflowing pipe 125 to be fixed, and thus is attached to be detachable,instead of being fixed by welding and the like. The reason is,particularly, because it is required to adjust a flow of the gas and theadjustments can be facilitated. Accordingly, intervals of the pluralityof cooling plates 126 are configured to be varied easily. In addition,for the plurality of cooling plates 126, it is shown in FIG. 16 that aplurality of rectangular plates is arranged from the gas introducingportion 122 side to the cooling medium supply mechanism 124 side, but asshown in FIG. 17, the plurality of cooing plates 126 may be arranged inparallel from the back to the front, as viewed in the figure.

Above the introducing portion 128 on the second space portion 127 side,for example, immediately above the portion 128 is disposed a heatingmechanism, for example, a heater 129 to heat the cooled gas flowing fromthe cooling portion 123 through the introducing portion 128 to apredetermined temperature, for example, substantially 23° C. To the sideof the heater 129 is disposed a blowing mechanism 130 that sends the gasof the space portion 127 to the substrate processing apparatus 1 via theports W1 to W4. A center height position CP of a rotation mechanism ofthe blowing mechanism 130, for example, of a rotation fan 131 isconfigured to be higher than an installation position of the heater 129to improve the efficiency in sending the wind. Further, in the secondspace portion 127, not shown in the figure, a humidity adjustmentmechanism is provided to set the gas inside the space portion 127 at apredetermine humidity. A control mechanism 135 of the gas utilityapparatus 120 is provided on the side opposite to the filter 121 of theapparatus 120, and configured to control the heater 129, cooling mediumsupply mechanism 124 and blowing mechanism 130 described above.

The gas utility apparatus 120 supplies the gas with adjusted temperatureand humidity to each of the antireflective film forming apparatuses HB,coaters COT and development processing apparatuses DEV via the pipe 110,as described above. For the configuration of the antireflective filmforming apparatus HB and/or coater COT, as shown in FIG. 18, theapparatus HB and/or coater COT is provided inside the apparatus with arotation member 140 that holds the semiconductor wafer W to rotate, anda cup 141 surrounding the rotation member 140. Above the cup 141 isprovided a gas supply apparatus 142 having a width H9 in the verticaldirection to send the gas supplied from the pipe 110 to the direction ofthe cup 141. Further, the gas supply apparatus 142 has rectifyingmechanisms 143 that send the down-flow with high accuracy. Furthermore,the distance between the gas supply apparatus 142 and the position ofthe upper face of the cup 141 is set at a distance of H10.

For the configuration of the development processing apparatus DEV, asshown in FIG. 19, the apparatus DEV is provided inside the apparatuswith the rotation member 140 that holds the semiconductor wafer W torotate, and the cup 141 surrounding the rotation member 140. Above thecup 141 is provided a gas supply apparatus 144 having a width H9 in thevertical direction to send the gas supplied from the pipe 110 to thedirection of the cup 141. The gas supply apparatus may have rectifyingmechanisms, but a lower degree of accuracy than that of theantireflective film forming apparatus HB and coater COT is enough, andthe rectifying mechanisms are not required particularly. It is thuspossible to limit the vertical length of the development processingapparatus DEV to a length smaller than the vertical length of theantireflective film forming apparatus HB and/or coater COT. Accordingly,the vertical length of the gas supply apparatus 144 is configured to besmaller than the vertical length of the gas supply apparatus 142.Further, the distance hl2 between the gas supply apparatus 144 and theposition of the upper face of the cup 141 is set at a distance smallerthan the distance h10 described above.

For utility to each liquid processing apparatus of each of thehorizontal blocks HBB, COTB, DEVB1 and DEVB2 of respective liquidprocessing apparatuses, a utility apparatus disposed outside thesubstrate processing apparatus 1 supplies each utility. As shown in FIG.20, for the HBB and COTB, a utility apparatus 170 supplies apredetermined processing liquid, for example, resist solution, and aninert gas, for example, N₂. For the DEVBs, a utility apparatus 171supplies a predetermined processing liquid, for example, developingsolution, and pure water and the like. Described first is about thehorizontal blocks HBB and COTB. The utility apparatus 170 as a COTchemical cabinet sends utility set for a predetermined temperature, forexample, a processing liquid, for example, a resist solution (as theutility, the gas, for example, N₂ is in the same configuration, anddescriptions thereof are omitted) to ports PC1 a and PC2 a on thesubstrate processing apparatus 1 side from ports PC1 and PC2,respectively. It is configured that branch mechanisms PC1 b and PC2 beach comprised of a valve and the like on the substrate processingapparatus 1 side are capable of supplying the utility from the ports PC1a and PC2 a to each liquid processing chamber of the horizontal blocksHBB and COTB, respectively.

Described next is about the horizontal blocks HBBs. The utilityapparatus 171 as a DEV chemical cabinet sends utility set for apredetermined temperature, for example, a processing liquid, forexample, a developing solution (as the utility, another processingliquid, for example, pure water is in the same configuration, anddescriptions thereof are omitted) to ports PD1 a and PD2 a on thesubstrate processing apparatus 1 side from ports PD1 and PD2,respectively. It is configured that branch mechanisms PD1 b and PD2 beach comprised of a valve and the like on the substrate processingapparatus 1 side are capable of supplying the utility from the ports PD1a and PD2 a to each liquid processing chamber of the horizontal blocksDEVBs, respectively.

For supply of utility, for example, a predetermined processing gas, forexample, a gas such as HMDS and the like, to each AD of the horizontalblock ADB of ADs of the heaters, as shown in FIG. 21, the utilityapparatus 170 disposed outside the substrate processing apparatus 1 asthe COT chemical cabinet is configured to be shared with theabove-mentioned configuration. The utility apparatus 170 sends theutility set for a predetermined temperature, for example, the gas suchas HMDS and the like to a port PC3 a on the substrate processingapparatus 1 side from a port PC3. A branch mechanism PC3 b comprised ofa valve and the like on the substrate processing apparatus 1 side isconfigured to be able to supply the utility from the port PC3 a to eachheater of the horizontal block ADB of heaters ADs. Further, thesubstrate processing apparatus 1 is provided with a control mechanism180 and further with a main operation mechanism 181 and sub-operationmechanism 182. The utility apparatus 170 has a control mechanism 183 andoperation mechanism 184, and the control mechanisms 183 and 180 areconfigured to convey information via a communication line 185 ascommunication means. The sub-operation mechanism 182 and operationmechanism 184 are configured to perform the same operation inpredetermined operation. The same operation is operation used inperforming maintenance such as dummy dispense, step control and thelike. In addition, another external utility apparatus may have such anoperation mechanism, but it is preferable that the substrate processingapparatus 1 and utility apparatus 170 as the COT chemical cabinet onlyhave at least such a function.

Described next is the processing operation of the resist processingapparatus 1 configured as described above. First, a worker or cassettecarrying robot places a cassette C storing a plurality of unprocessedsemiconductor wafers W in a cassette mount section U1 of the cassetteunit section CU. Then, the substrate carrying in/out mechanism 2 of thesubstrate carrying in/out mechanism section U2 carries the semiconductorwafers W out of the cassette C on a sheet basis, once adjusts theposition of the semiconductor wafer W, and delivers the semiconductorwafer W to the substrate delivering/receiving section 8 of the processunit section PU.

Then, the semiconductor wafer W is carried to the substratedelivering/receiving station 20 from the substrate delivering/receivingsection 8 by the substrate carrying mechanism TR1. Subsequently, thesubstrate delivering/receiving station 20 travels to a predeterminedheight position of the horizontal block HBB region in the verticaldirection, and the semiconductor wafer W is carried to a predeterminedAD section in the heater section by the arm 11 of the substrate carryingmechanism 10 in the horizontal block HBB region, and undergoeshydrophobic processing in the AD section. Then, the semiconductor waferW is carried from the AD section to the heater HP in the horizontalblock HBB region by the arm 11 of the substrate carrying mechanism 10 inthe horizontal block HBB region, further carried to the heatingprocessing mechanism 61 via the temperature adjustment mechanism 60 ofthe heater HP, and processed at a predetermined temperature. Thesemiconductor wafer W subjected to the heating processing in the heatingprocessing mechanism 61 is adjusted in temperature to a predeterminedtemperature, substantially 23° C. by the temperature adjustmentmechanism 60, and carried from the heater HP by the arm 11 of thesubstrate carrying mechanism 10 in the horizontal block HBB region.

Further, the semiconductor wafer W is carried to a predeterminedtemperature adjustment section COL in the horizontal block HBB by thearm 11 of the substrate carrying mechanism 10 in the horizontal blockHBB region, and adjusted in temperature to a predetermined temperature,substantially 23° C. Then, the semiconductor wafer W is carried from thetemperature adjustment section COL by the arm 11 of the substratecarrying mechanism 10 in the horizontal block HBB region, and moved tothe direction of the liquid processing apparatus in the horizontal blockHBB by the substrate carrying mechanism 10 rotating. Subsequently, thesemiconductor wafer W is carried to a predetermined liquid processingapparatus HB, and an antireflective film is formed on the processingsurface of the semiconductor wafer W. Then, the semiconductor wafer W iscarried from the liquid processing apparatus HB by the arm 11 of thesubstrate carrying mechanism 10, carried to a heater HP of the heatersection by the arm 11 of the substrate carrying mechanism 10 in thehorizontal block HBB region, further carried to the heating processingmechanism 61 via the temperature adjustment mechanism 60 of the heaterHP, and processed at a predetermined temperature.

The semiconductor wafer W subjected to the heating processing in theheating processing mechanism 61 is adjusted in temperature to apredetermined temperature, substantially 23° C. by the temperatureadjustment mechanism 60, and carried from the heater HP by the arm 11 ofthe substrate carrying mechanism 10 in the horizontal block HBB region.Further, the semiconductor wafer W is carried to a predeterminedtemperature adjustment section COL in the horizontal block HBB region bythe arm 11 of the substrate carrying mechanism 10 in the horizontalblock HBB region, and adjusted in temperature to a predeterminedtemperature, substantially 23° C. Then, the semiconductor wafer W iscarried from the temperature adjustment section COL by the arm 11 of thesubstrate carrying mechanism 10 in the horizontal block HBB region, andcarried to the substrate delivering/receiving station 20 or 21 by thesubstrate carrying mechanism 10.

The substrate delivering/receiving station 20 or 21 travels to a lowerposition, halts in a delivering position for the arm 11 of the substratecarrying mechanism 10 in the horizontal block COT region, and deliversthe semiconductor wafer W to the arm 11 of the substrate carryingmechanism 10 in the horizontal block COT region. In the horizontal blockCOT region, the processing steps are performed as in the processing inthe HBB, but the processing steps for AD may be selected as appropriatewhen necessary. The semiconductor wafer with the processing in thehorizontal block COT region finished is carried to the substratedelivering/receiving station 21 and carried to the substratedelivering/receiving section 9 by the substrate carrying mechanism TR2.The semiconductor wafer W is delivered to the interface unit section IFUvia the substrate delivering/receiving section 9, further delivered tothe exposure apparatus 3 via the substrate carrying in/out mechanism 6from the interface unit section IFU, and subjected to the exposureprocessing.

The exposure-processed semiconductor wafer W is delivered to theinterface unit section IFU, and then, carried to the heating processingmechanism FH by the substrate carrying in/out mechanism 6. In theheating processing mechanism FH, the semiconductor wafer W is deliveredto the temperature adjustment mechanism 60 of the heating processingmechanism FH, and undergoes heat treatment at a predeterminedtemperature e.g. a first temperature in the heating mechanism 61. Then,the semiconductor wafer W is delivered to the temperature adjustmentmechanism 60 from the heating mechanism 61, and after the temperature ofthe semiconductor wafer W reaches a predetermined temperature in thetemperature adjustment mechanism 60, carried to the substratedelivering/receiving section 9 by the substrate carrying in/outmechanism 6. The reason why the heating processing mechanism FH is thusdisposed in the interface unit section IFU is because of controlling thetime the exposure processing is performed in the exposure apparatus 3and making the time between the exposure processing in the exposureapparatus 3 and heat treatment constant in each processing targetsubstrate. By this means, the yield of processing target substrates isenhanced.

Then, the semiconductor wafer W is carried to the substratedelivering/receiving station 21 by the substrate carrying mechanism TR2via the substrate delivering/receiving section 9.
